Abstract
A pressure oil injector assembly characterized by novel features of construction and arrangement providing easy and quick mounting and dismounting and which has good transportability comprising an attachment and connecting member with connections for a pump housing of a pressure medium pump and a pressure pipe. The mounting arrangement is such that the high pressure side of the pump in in communication with the pressure pipe. The pump housing and pressure pipe are connected to the attachment and connecting member by means of threaded dowels which seat in threaded bores in the attachment and connecting member which are opposed to each other and spaced by a chamber or aperture. In the principal embodiment, a manometer seats in the aperture with a certain amount of play and is supported in a firm position between the inner terminal ends of the dowels. Accordingly, the angular position of one of the dowels and therefore, also the angular position of the pump can be freely chosen in relation to the attachment and connecting member and the parts including the manometer can be firmly connected in a leakproof manner simply by tightening the other dowel.
